.. previously I had STM32MP157D-DK1 on work, there DFU works Ok,
but now bought STM32MP157F-DK2 for home, there's no any sign of connection,
reset button do not affect on STlink led, meanwhile stlink/2 itself - works and other USBs - is Ok.
Maybe it's a problem of attached LCD or any jumper should be on (except Boot1/2+reset)
Another guess: I downloaded several times a new firmware into onboard stlink,
so maybe thus killed a "special" firmare for Stm32F1xx for DFU loaded for MP1,
so like AN2606 it recommends.
Regards.
PS: I cant believe its is a "congenital" defect of the product.
